Add vs. remove, and which one you need

Have a pre-tax price and need the final amount a customer pays? Use Add GST. Have a final price, say from a receipt, and need to work out how much was tax? Use Remove GST. The math runs in opposite directions, which trips people up if they pick the wrong mode.

CGST/SGST vs. IGST, simply put

For a sale within the same state, GST splits evenly between CGST and SGST. Across state lines, the full rate goes as a single IGST charge instead. The total tax rate stays the same either way, just structured differently depending on where buyer and seller sit.

Frequently Asked Questions

What's the difference between Add GST and Remove GST?

Add GST starts from a pre-tax amount and calculates the final price. Remove GST starts from a final price and works backward to find the taxable value.

How is tax split between CGST and SGST decided?

Intra-state transactions split the total GST rate evenly between CGST and SGST. Inter-state charges the full rate as IGST instead.

Which GST rates are supported?

The standard Indian slabs: 5%, 12%, 18%, and 28%.

Can I use this to double-check a supplier's invoice?

Yes, enter the taxable value and rate shown on the invoice and confirm the tax amount matches what was actually charged.
